我完全不了解 MEAN Stack,并且在使用 Angular 的 Material 模块时遇到了一些问题。 我正在尝试在代码中导入 "@angular/material" 模块,但是每当我导入它时都会出现错误。 错误如下:
ERROR in src/app/app.module.ts:5:32 - error TS2306: File '/Users/anmolsarraf/Desktop/MEAN Stack/mean-course/node_modules/@angular/material/index
.d.ts' is not a module.
这里是我的 package.json 文件:
{
"name": "mean-course",
"version": "0.0.0",
"scripts": {
"ng": "ng",
"start": "ng serve",
"build": "ng build",

"protractor": "~5.4.0",
"ts-node": "~7.0.0",
"tslint": "~5.15.0",
"typescript": "~3.5.3"
}
}
这是我的app.module.ts文件:
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { MatInputModule } from '@angular/material/input';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { PostCreateComponent } from './posts/post-create/post-create.component';
@NgModule({
declarations: [
AppComponent,
PostCreateComponent
],
imports: [
BrowserModule,
AppRoutingModule,
FormsModule,
BrowserAnimationsModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
确切地说,我正在尝试执行import { MatInputModule } from '@angular/material';
,但是遇到了上述错误。我已经尝试将上述模块导入为
import { MatInputModule } from '@angular/material/input';
,但是它会抛出一堆错误,说node_modules/@angular/material/input/input.d.ts:138:9 - error TS1086: An accessor cannot be declared in an ambient context.
任何帮助都将不胜感激。谢谢!更新
我创建了一个Angular应用程序的新实例,然后尝试在其中导入Angular材料,某种方式它可以正常工作,因为我在导入时没有遇到任何错误。谢谢!
npm install
命令? - JD Davis@angular/material
是v9而Angular是v8,但不完全确定。您能确保Angular和Angular Material的版本相同吗?(删除node_modules,重新安装等) - Phix
